FLOOR-JAG K.

SPECIFICATION forming part of Letters Patent No. 702,837, dated June 1'7, 1902.

Application filed February 23,1901. Serial No. 48,417- (No model.)

To all whom it may concern.-

Be it known that I, ROELF JOHNSON WEI- LAND, a citizen of the United States, residing at Canastota, in the county of McCook and State of South Dakota, have invented a new and useful Floor-Jack, of which the following is a specification.

My invention relates to floor-jacks of that class in which are employed levers, &c., for holding the boards while being nailed and means for forcing the boards into position; and the present invention has for its objects, among others, to provide an improved, simple, and cheap floor-jack of thischaracter by which crooked and warpy boards may be straightened and laid without injury to the boards and also to so construct and assemble the parts that the device may be easily operated and not liable to get out of order or broken.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a front elevation of the improved floor-jack. Fig. 2 is a side elevation thereof. Fig. 3 is a perspective view of the same with the parts in operative position.

Like numerals of reference indicate like parts throughout the different views.

Referring now to the details of the drawings, 1 designates the tongs, the two parts of which are pivoted together at 8 and their jaws provided with the pegs 9.

3 is the catch-dog fork, mounted at one end on the pivot 8, and in this fork is the socket or recess in which is disposed the catch-dogfork base 2. at is a catch-dog pivoted at 6 in the said fork 3. The base 2 is held in the fork by a rivet 7.

10 is a lug in which is a bolt 11, serving as a pivot for the leg 5, the free end of which is split or bifurcated, as shown, and the split ends are provided with the thumb-screw 12, which serves a purpose which will soon be made apparent.

In use the pegs 9 are forced into the joist or scantling, (indicated by dotted lines in Fig. 3,) and then the leg 5 is placed on the board, the catch-dog 4 is placed against the joist or scantling, as indicated in said Fig. 3, when by forcing the tongs together and pressing downward the board will be pressed down to its place. Then the hands may be taken from the tongs, the sharp end or the dog4 engaging in the joist and securely holding while the board is being nailed. After the nailing is finished all that is necessary to do is to press down on the tongs with one hand and pull the catch-dog at back from the joist with the other hand and then open the tongs and extend them ready for the next board, when the operation is repeated, and so on till all the boards have been placed in position and nailed. Before using the floor-jack a block about twoinches square, more or less, is placed in the bifurcation of the leg 5 and then the thumb-screw turned to securely hold the said block in place. This block prevents battering or marl-ing of the edge of the board. The nature of the block should be varied in accordance with the character of the material being operated upon.

It will thus be seen that I have provided a simple and cheap device by Which crooked and warpy boards may be easily and quickly and satisfactorily laid and by which they may be held while being nailed.

What is claimed as new is 1. In a floor-jack, the combination with the tongs, of the leg pivotally mounted thereon,

the catch-dog fork pivotally mounted on the pivot of the tongs and the catch-dog pivotally mounted on saidfork, all substantially as shown and described.

2. In a floor-jack, the combination with the tongs, of the leg pivotally mounted thereon, the catch-dog fork pivotally mounted on the pivot of the tongs, the catch-dog base secured thereto, the catch dog pivotally mounted thereon on a pivot at right angles to the pivot of the fork, and the pegs carried by the jaws of the tongs, as set forth.

3. In a floor-jack, the combination with the tongs and the leg pivotally mounted thereon, of the catch-dog base, the catch-dog fork to which the same is secured pivotally mounted on the pivot of the tongs and the catch-dog pivotally mounted on said fork, all substantially as described.

4L. In a floor-jack, the combination with the to the plane of movement of the dog, as shown tongs, of the leg pivotally mounted thereon and described. and bifurcated and provided with a thumb- In testimony whereof I have signed my screw, the catch-dog fork pivotally mounted name to this specification in the presence of 5 on the pivot of the tongs, the catch-dog base two subscribing witnesses. secured within a mortise therein, and the T catch-dog pivotally mounted on said fork, ROELF JOHI\S()N VEILAND' the dog and leg being upon opposite sides of Witnesses: the tongs to move in opposite directions, and PETER BRUNES PETERSEN, IO the fork movable on its pivot at right angles l GEO. A. VAN WOERT.
